T0 aZZ whom, it may concern:

Be it known that I, ISAAC W. NUMAN, a citizen of the United States,residing at Oan ton, in the county of Stark and State of Ohio, haveinvented certain new and useful Improvements in Sheet-Metal-CorrugatingMachines; and I do hereby declare that the following is a full, clear,and eXact description of the same, reference being had to the anneXeddrawings, making a part of this specification, and to the numerals ofreference marked thereon, in which- Figure 1 is a front elevationshowing the corrugating-rolls in normal position. Fig. 2 is an end viewshowing the right-hand end of Fig. 1. Fig. 3 is a view showing portionsof the rolls and a sheet of metal partially corrugated. Fig. 4 is atransverse section on line A A, Fig. 1. Fig. 5 is a transverse sectionof the rolls, showing the rolls spaced from each other or out of meshand illustrating a plain column on the upper roll. Fig. 6 is a perspective view showing the upper roll swung out and in position toreceive a plain column or tube and illustrating a column or tube locatedthereon. Fig. 7 is a View showing a portion of the frame bearing orstandard and illustrating the bearing-head, showing the upper bearingopen. Fig. 8 is an enlarged transverse section showing a modified formof the rolls from the ones shown in Figs. 4 and 5. Fig. 9 is a detachedview of the rotary bearing-head for the upper roll.

The present invention has relation to machines designed to corrugate,flute, or place ornamental designs upon tapered columns; and it consistsin the novel arrangementhereinafter described, and particularly pointedout in the claims.

Similar numerals of reference indicate corresponding parts in all thefigures of v the drawings.

In the accompanying drawings, 1 and 2 represent the upright end members,which are spaced apart equal to the length of the corrugating-rolls, orsubstantially so, and of course are held in proper parallel position attheir bottom or lower ends in any convenient and well-known manner, andtheir top or upper ends tied together by means of the tie bar or beam 3.The lower corrugating-roll 4 is properly journaled in the uprightmembers 1 and 2, which roll is provided with the shaft or bearings 5,and the outer ends of the shaft or bearing provided with the gear-wheels6 and 7. Directly above the lower corrugating-roll 4 is located theupper corrugatingroll 8, which upper corrugating-roll is provided withthe shaft or bearing 9, one end of said shaft being journaled in therotary and movable head 10 and the opposite end of said shaft adapted tobe located in a suitable bearing, which bearing is formed by means ofthe semicircular recesses 11 and 12, the recess 11 being formed in themovable head 13 and the recess 12 formed in the hinged cap 14, saidgrooves being so located with reference to each other and the hinged capso at" tached that when said cap is closed or connected at its bottom orlower end to the head 13 a proper bearing will be provided for the shaft9 at the end of said shaft where said bearing is located. Thecorrugating-rolls 4 and 8 are each tapered and are provided with taperedcorrugations upon their peripheries, the size and shape of thecorrugations corre sponding in size and shape with the corrugations tobe formed in the column.

It is well understood that in order to produce a tapered column and tocorrugate the same it is necessary to provide means by which thecorrugations can be made Without buckling the metal and at the same timeproduce corrugations that will be properly tapered, so as to give apleasing effect to the eye, and at the same time produce a perfect andproperly-finished corrugated column. In order to provide for thedifficulty just above described, I provide two tapered rolls, the taperof the rolls to correspond, substantially, with the taper designed andcalculated to be given to the finished column. In use I prefer toconstruct a plain tapered cylinder or skelp, such as illustrated in Fig.6, and in order to place the same upon one of the corrugating-rolls itis necessary to swing the corrugating-roll so as to permit the skelp tohe slipped over and upon the roll. In order that this may beaccomplished, I provide the head 18 with the hinged bearing-cap 14,thereby providing a means for opening the bearing proper and allow theroll to be swung. It will be understood that when the gearwheel 6 andthe gear-wheel 15 are held in mesh with each other it would beimpossible to swing one of the rolls so as to bring it out of horizontalparallelism with the remaining roll, and in order to provide for boththe swinging of the roll and throwing the gearwheels 6 and 15 togetherwith the corrugations of the rolls themselves, the movable and rotaryhead 10 is provided. The heads and 13 are so attached to the uprightmembers 1 and 2 that they are capable of longitudinal movement, and forthe purpose of imparting longitudinal movement to said heads they areeach provided with the toothed flanges 16 and 17, which toothed flangesare preferably formed integral with the upper portions of the heads'lOand 13; but of course they may be made separate and attached in anyconvenient and well-known manner. To the flanges 18, formed upon the tiebar or beam 3, are pivotally attached the levers 19 and 20, which leversare provided with the toothed segmental ends 21 and 22, which toothedsegmental ends mesh with the toothed flanges 16 and 17, as illustratedin Figs. 1 and 6. To the inner ends of the levers 19 and are pivotallyattached the top or upper ends of the rods 23, which rods are attachedat their bottom or lower ends to the links or throw-bars 24, whichthrow-bars and links are connected together by means of the cross-bolts25, which cross-bolts pass through the slots 26, formed in the rockinglevers 27, which rocking levers are pivotally attached intermediatetheir ends to the fixed flanged plates 28 or their equivalents. When itis desired to give an upward movement to the heads 10 and 13, therocking levers 27 are moved downward at their outer ends, there bymoving the rods 23 downward with the downward movement of said rockinglevers, which in turn moves the inner ends of the levers downward andthe toothed segmental ends upward, thereby moving the heads 10 and 13upward, which movement throws the gear-wheels 6 and 15 out of gear andalso the corrugating ribs of the rolls 4 and 8 out of mesh, at whichtime the hinged bearing 14 can be released and the roll 8 swung into theposition illustrated in Fig. 6.

For the purpose of holding the rocking levers 27 down they are tiedtogether by means of the tread-bar 29, and the tread-bar held downtogether by means of the toothed bar 30, which toothed bar is held infixed position upon the floor or other object. For the purpose ofproviding means for releasing the tread-bar 29, so that it can moveupward, the toothed bar should be formed of spring material, so that itcan be forced backward or away from the tread-bar 29, so as to disengageit from said tread-bar. When it is desired to move the heads 10 and 13downward, the throw-bars 24 are moved so as to bring their ends to whichthe rods 23 are attached upon the opposite sides of the pivotal pointsof the rocking levers 27 this being accomplished by means of thecrank-rod 31 which crank-rod is provided with the footlevers 32, whichfoot-levers are formed integral or attached to the crank-rod 31, saidcrank-rod being journaled in suitable flanges 33, which flanges arelocated upon the treadbar 29. It will be understood that the crossbolts25 move in the slots 26 during the time the throw-bars 24 are moved ineither direction. It will be understood that after the rods 23 have beenshifted, so as to bring their lower or pivoted ends upon the oppositesides of the pivotal points of the rocking levers 27 from their positionshown in Fig. 6, that a downward movement of the tread-bar 29 will movethe inner ends of the levers 19 and 20 upward and their toothedsegmental ends downward, thereby moving the heads 10 and 13, togetherwith the different parts carried thereby, and the rolls 4 and 8 intoproper contact with each other to corrugate a column and'at the sametime bring the gearwheels 6 and 15 into roper mesh. It will beunderstood that it is necessary to impart a rotary or axillary movementto the head 10 in order to swing the roll 8, and in order to hold thetoothed flange 16 and the toothed segmental ends of the lever 20 in meshthe teeth of the toothed flange 16 are formed of sufficient width toallow a partial rotary movement of the head 10 and at the same timemaintain the mesh as between said toothed flange and its engagingtoothed segmental head.

For, the purpose of maintaining a uniform mesh regardless of theposition of the toothed flange 16 the outer ends of the teeth are con- 95 vex, as best illustrated in Fig. 9.

In Fig. 8 I have illustrated a modified form of a corrugating-roll,which consists in removably attaching the corrugating ribs 34 to theperipheries of the roll.

For the purpose of holding the bearing-cap 14 up and out of the wayduring the time the roll 8 is swung out of alinement with the roll saidbearing-cap is provided with the spring 34% For the purpose of holdingthe cap 14 down and in a closed position so as to provide a suitablebearing for the free end of the upper roll the screw-threaded bolt 35 isprovided, which screw threaded bolt is adapted to enter thescrew-threaded aperture 36, formed in the head 13.

For the purpose of insuring the skelp to rotate with the rotation of thecorrugating-roll upon which it is mounted said corrugatingroll isprovided with the groove 37, which groove is for the ur ose of receivingthe locked seam 38 of t e s :elp 39.

For the purpose of imparting rotary movement to the rolls thepower-shaft 40 is provided, which power-shaft may be located as shownand is provided with the power-wheel 41 and the gear-wheel 42.

For the purpose of preventing any lagging or twisting as between thecorrugating-rolls at their opposite ends to that which power is directlyapplied the gear-wheels 7 and 43 are provided, by which arrangement theshafts upon which the corrugating-rolls are mounted will be rotated inunison.

In Fig. 8 the shaft 8 is provided instead of I 30 the roll proper andthe cylinder 9 mounted thereon. This is simply a modification as t theconstruction of the roll.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
